I recently took the plunge and shrunk my laptop ssd drive to accommodate Mint. Actually I am a long time Mint user, but was a bit nervous dealing with the new UEFI format. Anyways it all went well. Also my ageing PC crashed and I built a new one with a B360 HD3 MB and an i5-8400 CPU with 16GB RAM.
I have a question. The laptop boots in 12 seconds. The PC is about 30 seconds and still multiple times faster than Windows 10. This is not a complaint, but I'm curious as to why my laptop boots Mint a couple of times faster than my PC. The laptop is a Dell Inspiron 15-5578.

the more hardware you have installed the longer the boot will be. i have 5 spinning drives and settled for slow boot a while back but around 30-45 seconds is fine for me. sometimes when things are updating 1 minute is also fine

@AllanPen
reboot a few times and check again dmesg | grep -i "error\|warn\|fail" some errors may be gone . ACPI errors are common but not so many. updating kernel can remove some but also new errors appear.
